You can use it to retrieve metadata of OASIS Standards from https://www.oasis-open.org/standards/ and access such metadata through the Relaton::Oasis::ItemData object.

Add this line to your application’s Gemfile:

gem 'relaton-oasis'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install relaton-oasis

Usage

Get standard using reference.

All the OASIS documents are parsed from https://www.oasis-open.org/standards/ and stored in a GitHub repository https://github.com/relaton/relaton-data-oasis. You can find all possible references on the index page https://relaton.github.io/relaton-data-oasis/.

require 'relaton/oasis'

item = Relaton::Oasis::Bibliography.get "OASIS amqp-core"
[relaton-oasis] INFO: (OASIS amqp-core) Fetching from Relaton repository ...
[relaton-oasis] INFO: (OASIS amqp-core) Found: `OASIS amqp-core`

XML serialization

item.to_xml
=> "<bibitem id="OASISamqpcore" type="standard" schema-version="v1.4.1">
      <fetched>2026-02-27</fetched>
      <title language="en" script="Latn" type="main">Advanced Message Queueing Protocol (AMQP) v1.0</title>
      <docidentifier type="OASIS" primary="true">OASIS amqp-core</docidentifier>
      ...
    </bibitem>"

item.to_xml bibdata: true
=> "<bibdata type="standard" schema-version="v1.4.1">
      <fetched>2026-02-27</fetched>
      <title language="en" script="Latn" type="main">Advanced Message Queueing Protocol (AMQP) v1.0</title>

        <flavor>oasis</flavor>
        <technology-area>Messaging</technology-area>
      </ext>
    </bibdata>"

Fetch data

The OASIS documents can be fetched from https://www.oasis-open.org/standards/ and converted into RelatonXML/BibXML/BibYAML formats:

The method Relaton::Oasis::DataFetcher.fetch(output: "data", format: "yaml") fetches and converts all the documents from the https://www.oasis-open.org/standards/ and saves them to the ./data folder in YAML format.

Arguments:

• output - folder to save documents (default './data').

Logging

RelatonOasis uses the relaton-logger gem for logging. By default, it logs to STDOUT. To change the log levels and add other loggers, read the relaton-logger documentation.

Development

After checking out the repo, run bin/setup to install dependencies. Then, run rake spec to run the tests. You can also run bin/console for an interactive prompt that will allow you to experiment.

To update the index test fixture (used by tests), run rake spec:update_index. This downloads the latest index-v1.zip from the relaton-data-oasis repository.

To install this gem onto your local machine, run bundle exec rake install. To release a new version, update the version number in version.rb, and then run bundle exec rake release, which will create a git tag for the version, push git commits and the created tag, and push the .gem file to [rubygems.org](https://rubygems.org).
